Application filed October 13, 1920. Serial No. 416,598.

To (LIZ w/zom it may concern:

Be it known that I, Grocer ll". lVn-LLs, a citizen of the United States, resident of Amesbury. in the county of Essex and State of Massachusetts. have made a certain new and useful Invention in \Vind'ow Regulators; and I declare the following to be a full, clear, and exact description of the same. such as will enable others skilled in the art to which it appertains to make and use the invention, reference being bad to the a companying drawings, and to letters or figures of reference marl-zed thereon, which form a part of this specification.

Figure l; is a face view of the invention, as applied, with parts broken away.

Figure is a detail face view of the spring jaws and parts adjacent thereto.

Figure Figure 1.

Figure 4 is a section on the line l-4, Fig ure 1.

Figure 5 is a section on the line 55, Figure 1.

The invention has relation to window reg ulators', designed for use in the raising and lowering of glass windows, primarily in closed automobile bodies, an object being to provide means formaintaining the window in position as adjusted for height at any point in the movement thereof, as also to provide durable, eflicient and easily operable means for the purpose. Other objects and advantages will appear.

The invention consists in the novel construct-ion and combinations of parts as hereinafter set forth.

In the accompanying drawings illustrating an embodiment of the invention, the numeral 2 designates the pillars of the window frame, provided with lateral channeled guides 3, 3, slidably engaged by the lateral edges of the glass window 4, one of said pillars being provided, below the window opening 5, with a vertical rod 6, rigidly at tached to the pillar at its upper and lower ends.

The lower edge of the glass window is en gaged within the longitudinal recess of a channeled metal strip 7, a lever 8, being pivoted at its lower end at 9 to one of said pillars, and at its upper end having a roller 10, slidably engaging the strip 7, a counterbalancing coiled spring 11, being its upis a section on the line 3-3,

peren'd at 12 attached to the cross piece 13 of the window frame, and at its lower end adjnst a'bly engaging anyone of a series of notches H. of said lever.

Slidably engaging the rod 6 is a head 15, having upper and lower outwardly converging flanges t6, provided with perforations 1T loosely engaging the rod, upper and lower spring plates or jaws 18, extending in opposed oblique relation to said rod, being secured each at its outer end at 19 to the related flange and at its free end having a recess ii) the marginal edge of which normally "engages the rod. Owing to the op-- posed oblique relation of the springs 18 to the rod 6, the marginal' edges of the recesses 20 will have a binding or biting engagement with said rod, the one preventing movement of said headdownwardly andthe other preventing movement upwardly. The head 15 is provided with a horizontal channeled extension :21, engaging one end portion of the metal strip 7, whereby movement of the glass window both downwardly and upwardly-is also-normally prevented.

The spring jaws 18, being under tension, create a thrust between the head 15 and the rod 6 which will draw the walls of the perforations 17 into engagement with said rod upon the side thereof opposite that engaged by the spring jaws. Thus the parts will be held firmly together and will not be affected by the vibration of the vehicle, which might otherwise displace them sufliciently to allowgrad'ual movement of the window or to wear the surface of the rod6 into corrugations I urtherm0re,since the tension of the spring jaw causes an engagement upon opposite sides of the rod, the operation of release, movement and reengagement will be perfectly smooth. j I

In order to release the bite or bind. of one of the spring jaws 18 upon the rod 6, to enable the window to be adjusted in the desired direction, a cylinder piece 22 slidably engages the rod 7 between the spring jaws, being circumferentially notched at its ends at 23, to receive the free ends of the jaws, movement of the jaws to release the same from the rod being permitted by the intervals 24, normally separating the jaws from the flanges 16.

The cylinder piece 22 is rigidly secured V to the lower end of an operating rod. 25, ex-

tending upwardly alon side of one of the guides 3, and provide at its upper end with an outwardly extending handle 26.

In operation, the window being closed, the operating handle is pushed downwardly to press the cylinder piece 22 downwardly and thereby first release the lower spring jaw 18 from the rod 6, after which the lower; end of the cylinder piece contacts with the lower flange 16 to move the head 15 and the horizontal extension 21. thereof downwardly, the channeled strip 7, being bolted to said extension at 27, and also being moved downwardly, the weight of the glass window being sufiicient to cause it to fall, release of the pressure upon the operating handle at once permitting the spring jaw to resume normal position and hold the window in position as adjusted.

The operatinghandle being pushed upwardly, the cylinder piece 22 will be moved upwardly therewith to thereby first release the upper spring jaw from the rod, after,

which the upper end of the cylinder'piece will contact with the upper flange 16, and the head 15 and the horizontal extension 2]. thereof will be moved upwardly, the spring 11 serving to materially assist in the raising of the window.

7 I claim 1. In means for adjusting and maintaining the adjustment of windows, a frame having guides, a glass movable therein, a rod, a head adapted to move the glass and slidable upon said rod and having an oblique spring jaw having binding engagement with said rod and adapted for release by movement to a position of greater obliquity relative to said rod, and an operating device adapted to contact with and more said jaw to a position of such greater obliquity, and thereafter to contact with said head and move the glass.

2. In means for adjusting and maintaining the adjustment of windows, a frame having guides, a glass movable therein, a

rod, a head adapted to move the glass and slidable upon said rod and having oblique spring jaws diverging from their points. of

connectionwith said head towards and hav-= ing binding engagement with said rod, said jaws being each releasable by movement in.

and. adapted by movement in one or the other direction to contact with the inner side of and to release one or the other jaw and thereafter to contact with said head and move the glass accordingly.

3. In means for adjusting and maintain ing the adjustment of windows, a frame, a glass movable therein, a vertical rod, a head having rigid connection with the glass and upper and lower flanges, and .wjflii'ifl' jaws of oblique relation to and having binding engagement with said rod to prevent both downward and upward movement of the glass and to hold it at any point in its movement, said jaws being coimected. at their outer ends to said head and spaced apart at their ends from said flanges to admit of movement of release from said rod, and an operating device having a lower cylinder picre engaging said rod between said jaws and having circumferential end notches, said jaws bearing upon the circumferential. walls of said notches and said cylinder piece being movable aiong the rod to release the upper or the lower aw and thereafter having contact with the upper or the lower of said flanges to raise or lower the window according to the direction of movement.

4. In means for vertically adjusting and maintainin the adustment of windows a frame having vertical guides, a glass slidable therein, a vertical rod, a head having an extension projecting under and supporting the glass and a lower flange, a spring aw of oblique relation to and having blndng engagement with sald rod to prevent downward movement of the glass and to hold it at any point in its movement, said jaw being connected at its outer end to said flange and spaced apart from the same,'and an operating device having a lower cylinder piece engaging said rod having a lower end notch, said jaw bearing upon the circumferential wall of saidnotch, and said cylinder piece being'movablc along said rod to release said jaw and thereafter having contact with said flange to lower the window.

in testimony whereof I affix my signature in presence of two witnesses.

GEORGE W. WELLS.
